摘　　要：针对挖陇沟煤矿+970m主石门在强含水地层施工中,遭遇富含大量黏性黄泥、砂及高压力岩溶水的特大岩溶地质构造带,采用综合勘查技术、防喷及可控排放技术、带压帷幕注浆水害治理技术,攻克了掘进通过充水特大岩溶裂隙破碎带的难关,成功解决了煤矿井巷施工水害治理的难题。Aiming at the condition that Diglonggou Coal Mine ＋ 970m main cross-hole encounters the large karst geological structure problems of a large number of viscous yellow mud,sand and high pressure karst water in strong water bearing stratum construction,we use comprehensive exploration technology including blowout prevention and technology,controllable discharge pressure curtain grouting water treatment technology to capture the difficulty of tunneling through the large water-filled karst fracture zone,which successfully solves the problem of coal mine roadway construction of water control.
